To all whom t may concern.'

' Be it known thatl, Josnrri lDilemma; a subject of the King of Belgium, and resident of Liege, Belgium, 32 Rue Adolphe Borgnet, have invented certain new and usei'ul Improvements in or Relating to Gunlock Device of Smallarms; and l do hereby dcclare the following to be a ulhclear, and exact description oi' the invention, such will enable others skiiled in the art towhich it appertains to make and use the same, ret erence being had to the accompanying drawings, and to letters or figures oit reference marked therein, which form a part of this specification.

This invention relates to sinall-arn'is of the repeating or automatic type, and it reates particularly to a gun-lock device coinprising a trigger on which is pivoted a lever acting on the sear which cocks the striker.

In` the gun-lock device according to this invention the lever pivoted on the trigger acts on one end of a projection on the sear yand enters in a recess lowering in `front of 25 the said elevation soon after firing, thus allowing the scar to cock the striker again vwhen the breech bolt is recoiling.

The movements of the lever pivoted on the trigger may be controlled by' the motions of the breech bolt. For this purpose a secondlever pivoted on a magazine lug may be utilized, this second lever acting on the rst rlever above mentioned, and being provided with a finger the end of whicheir gages in a groove formed in the breech bolt.

When it is used with a tubular magazine disposed in the stock, the trigger may be arranged under this magazine and the sear above it, the lever pivoted on the trigger being on one side oi the .magazine and the lever pivoted on the magazine lug passing on the other side of it. i

The accompanying drawings illustrate th application of the invention to an automatic rifle.

In the drawings:

Fig. 1 is a longitudinal section of thev riile, this section showing the gun-lock device;`

Fig. 2 is a perspective view of the gunlock device;

Fig. 3 is an underneath perspective View of the gun-lock device;

Fig. 4L is a perspective view showing theA Fig. 5 shows in perspective the assembly of the gun-lock pieces with the tubular magazine; and

Fig. 6 shows in perspective the iront end of the sear.

Qn the trigger 2` pivoted at 10, a lever 1 is pivoted at 11. For firing this lever acts downwardly on a projection or elevation 12 provided on the scar 3, which scarl is pivoted at 13. The downward action ot' the lever 1 on the scar 8 pushes the nose 14% ot the sear down, thus releasing the striker 15, which theny moves to strike the firing-pin 25. When the breech bolt 5 is re'coiling, the groove 8 with which it is provided leaves the end of 'the .finger 7 which was engaged in it. The said finger isa part orn a lever 6 pivoted at 17 which acts by an arm 18 on the lever 1 pivoted onthe trigger,=when the` finger 7 is forced down by the recoiling of the bolt 5. The backward movement ot' the groove 8 pushes the end of the finger 7 out of it, thrusting said finger down and forcing the lever 6 to turn about its axis 17, its arm 18 thus acting against the lever 1 to make it turn in the direction indicated by the arrow X. This lever 1 upon leaving the p-rojection12 on which'itwas resting, is brought above the recess 4- so thatthe sear 3 acted upon bythe scar vspring 19 assumes a position allowing it to cock the striker 15 during the recoiling movement of the latter.

In order to prevent the lever 1 from coming againstk the bottom of the recess 4;, the

ypulling ofthe trigger may be limited by an appropriate abutment this abutment being intended to act in such a way as to prevent a lowered position of the lever 1 which would prevent the raising of the nose 14 of the sear to cock the striker. s v

When the breech bolt 5 has assumed its forward position and the trigger has been released, the said trigger acted upon by the trigger spring 9 resumes itsv initial position and the lever 1 acted by its spring 16 turns round its axis 11 thus bringing its inger back over the elevation 12 of the sear. By

this rotation or the lever 1, the lever 6 moves s i so that its iinger 7 again enters the groove 8 of the bolt 5.

Fig. 5 shows how the pieces of the described gun-lock device may be disposed around a tubular magazine 21; the trigger 2 under this magazine, the sear 3 above it, the lever 1 pivoted onk the trigger passing in one sideo'f it. and the lever other side. A

The safety device acts upon the Sear. 3 and'is made up of a detent 20 arranged in 6 passing on the vthe usual manner.

While the invention has been illustrated in what isconsidered its best applicationit may aivayfrom said'shoulder, andovei' a rigid part of the sear disposed between its Ypivoted center andv its operated extremity.

2. A gun-lock device for repeating smallarms comprising in combination ay trigger, a sear. having intermediate its ends an eleva-v tion adapted to be acted uponby a lever pivotedvon said trigger and -.acting.on said elevation to accomplish the firing, said scar in presence oi two Witnesses.
